I think the X1 would have taken and kept the lead in the US/UK if :
They kept the support for 360 pads/wheels/kinect1
Launched with BC
Launched @ $399 + game and no kinect.
They could have offered an updated Kinect down the line if they were so inclined, but bundling it @ $499 was a horrendous decision.
The 360 lead in the US was massive, and they totally botched it with the X1 launch. It's impressive they've recovered in the US/UK to a respectable degree, even if it came with substantial price cuts.
As for EU/ROW, they were never going to win, but their poor decisions and international marketing basically guaranteed they'd be blown out there, so that's a non-issue.
